Could anyone tell me if it is normal for the LS gearbox to use a bit of transmission fluid. I have run the car daily for 6 months and the level has gone down from halfway between empty and full to the lower level mark in approx 8000 miles. It is due to be replaced but i am just a bit worried that this is not normal and this is an indication that something is wrong.
many thanks in advance for any help on this matter.

I don't think the transmission uses fluid as you describe, are you checking in a consistent manner i.e engine hot every time.
Is the fluid clean [pinkish] with no burnt smell?

Hi,
As ROYT says its not really normal for the autobox to loose oil,id have a look under the rear of the chassis of your car to see if theres any sign of a fluid leak.You might find there gearbox doesnt drop any oil on the road when parked,but when on the move theres a small fluid leak from the autobox under pressure when its working.Have a look at the exhaust pipe for signs of any fluid leak staining the exhaust.
Is there other problems with the autobox then as you say its due to be replaced.

A autobox should never use oil,to to go back to point made above,make sure you are checking the oil properly,ie hot and engine running.it makes a big difference.
